3. A box should contain exactly 64 matches. 100 boxes were checked and gave
the sample mean ī = 65 and sample standard deviation sioo = 25.
the sample mean ī = 66 and sample standard deviation sio0
= 25.
In each case verify the hypothesis H(m = 64).
[Ans. D = (-0, -2, 32) U (2.32, 0)] (a) 2 ¢ D hence we fail to reject ; (b)4 E D hence we reject
the hypothesis]
